The past isn't dead; it's not even the past. The South is still trying to win the Civil War, which should tell you a lot of what you need to know about the opposition to Barack Obama.
In any case, it's time to stop obsessing over the past and focus on the future. One way to start is by taking a look at this speech by John Kerry. I can't help thinking that, if he'd spoken more like this in 2004, he might have made it into the White House. Kerry was far from my favorite Democrat, but he would have been better than four more years of Bush-Cheney.
